%0 Journal Article %T A Simple Geometrical Model for Solid Friction %A T. Poeschel %A H. J. Herrmann %J Physics %D 1993 %I arXiv %R 10.1016/0378-4371(93)90233-T %X We present a simple model for the friction of two solid bodies moving against each other. In a self consistent way we can obtain the dependence of the macroscopic friction force as a function of the driving velocity, the normal force and the ruggedness of the surfaces in contact. Our results are discussed in the context of friction laws used in earthquake models. %U http://arxiv.org/abs/cond-mat/9306062v1
